Interesting thought about the labels. Mine mostly do not match.
In fact, on my keyboard, N is the most-obliterated key label, followed by MAD<. Also damaged: GHSECV. I think I can blame ASD on games, and E should be obvious. So why are CVNM< so very heavily worn? My best guess is that the labels are on the upper section of the keys, which is presumably the laziest part of the key for my fingers to reach?
